To all whom t may concern:

Be it known that I, WILHELM RoEDiiR, en-

' ineer a citizen of German residin at g a y:

Hanover, Germany, have invented new and useful Improvements inAutomatically-Operated Guns for Soaring Birds or Like Purposes, of whichthe following is a specification.

This invention relates to automatically operated guns for scaring birds,ysignaling or like purposes, of the type in which the lock-V ing membersof a series of striking bolts disl`posed side by side are operated byclockwork to release the striking bolts consecutively and so dischargethe cartridges.

In a previous construction the locking members after being released bythe clockwork hadto be replaced singly by hand to retain the strikingbolts in their raised position, but this arrangement occupiedconsiderable time and there was alwa sa chance of the striking boltsbeing ine ciently `re-V tainedso-that the vibration of the apparatusafter the first cartridge had been discharged was liable to release someof the other strikwhenv the striking bolts had been properly made toengage their retaining members the vibration caused by firing loosenedtheremaining locking members which usually engaged grooves formed on thestriking bolts.

According to this invention these disadvantages are obviated by thelocking members being automatically forced into grooves on the strikingbolts by means of springs. Further, rotating tappets first employed formoving the striking mechanismV with such' Vguns in connection with aprimer band travcling under a striking member, are according to thisinvention used with a cam shaft for actuating the locking members. The

` arrangement according to the present invention is such that the devicecan be used in any position without danger'of premature show aconstruction of apparatus according release of the striking bolts, andfurther to reset the striking bolts it is merely necessary to .pull themupward into their raised position, their retention in this positionbeing automatically effected by the spring-conti'olled locking members;further any loosening of the retaining members is prevented by means ofthese springs.

In the accompanying drawings Vwhich to this invention, Figure l is across section taken on the line A-B of Fig. 2. Fig. 2

yadvance the plate z' the bolts f can freely is a plan. Fig. 3 is asection on the line C-D of Fig. 2, and Fig. 4 shows a cartridge carrierin side elevation.

A casing a is provided for clock-work ymechanism b which rotates aspindle c on which are mounted a number of tappets Z which successivelyshift locking members e when the spindle rotates so that the strikingboltsf are released and strike the pins of cartridges 7L in the carrierg. The locking members e carry plates z' which are slotted at k, thedimensions of the slot being such that when the striking bolts are intheir raised position as in Fig. 3 the eX- Ytremities of the plate z'engage grooves Z formed on the striking bolts. As soon, however, as thelocking member e has been moved against the action of its spring n topass through the widened portion of the slot if: under the action of acoiled spring m. Vhen the bolt has again been pulled up, the spring nforces the locking member e back intoits normal position and so movesthe plate into the position shown in Fig. 3

where it willengage the groove Z when the striking bolt is again raised.

The cartridge carrier or magazine g can easily be removed for purposesof i'e-chargingor cleaning; the clock-Work b may be disposed in thecenter of the casing a. or in 1 other desired position as may be foundmost convenient.

That I claim is:

l. A device of the character described, comprising a cartridge magazine,a series of spring-influenced bolts, a series of springinfluencedlocking-members adapted to engage tlie bolts, a rotatable spindle, andtappets on the spindle adapted to successively actuate thelocking-members.

2. A device of the character described, comprising a cartridge magazine,a series of grooved spring-influenced bolts, a series ofspring-influenced locking-members having elongated slots adapted toengage the bolts, a rotatable spindle, and tappets on the spindleadapted to successively actuate the locking-members.
